Thisinvention relates tofiwind'shields for vehicles of the kind in whicha transparentY *portion is movable to .provide a Ventilating aperture and has for its-objsctaconstruction of windshield and 'actuatingmechanism therefor which is practical-,from thestandf point of manufacture and ease of o-peration by an' v hiele. According to the inventionthewmd- U-shield comprises a plurality of'transparent sectionsv disposed in the same plane, one of which is Vmovable Vin that plane to afforda passage for air by ineansgof actuating mechanism includinga system 4of levers connected f5 with themovable section and so associated with spring meansthattlie springs resist the f tendencyv ofthe window't'o close and act as a `Vcounterpoise therefor. e The invention'w'ill 'now be described in greater particularity in '3W connection with the accompanying c lrawl 'ings' illustrating-7a preferred embodiment thereof', in which: y

Figure 2 is a transverse vertical sectional View taken in the plane indicated by the line..

2-2 in Figure 1, looking in the direction of the arrows and showing in detail the'actuating mechanism for raising and lowering the movable pane. v

Figure 3 is a the construction illustrated in Figure 2 in greater detail, parts being removedv or sectioned in the 'interestof clea-rness.

Figure 4 isa fragmentary view looking from above and showing the pivotal connecv y cilitates the raising thereof an'd tends to re- 'tion for the system of leverage'.

Y The movable pane of glass a lies'in the same plane as the remainder and stationary part of the windshield indica-ted at b inFigure 1 Vand is slidable vertically in grooves in the uprifflit frame members c. 0. Preferably the movable pane is guided by metallic guides cl comprising bifurcated members clamping the glass therebetween and having yielding nonmetallic material d interposed between glass and metal to cushion the glass against vibration.V Y

U The panera is raised or lowered by rotat- Y ing a handle e within-easy reach of the operator of the vehicle which turns through Vthe -co-operatingj spiral gears, e and f, a

' threaded rod f journaled at its upper end sa in a. bearing member g and reciprocating by occupant engaged in driving the ve-V fragmentary view showing` its motion'fanut l'whicli is guided in a e i gro-ovev forniediby the inwardly turned edges y i of the supporting member c". The metallic cross fran'ieniember a securedto the top of the movable pane a is connected to the reciprocating 'nut z/by means'of levers' j, having' a lost motion connection with tlieframe member a. These levers extend upwardly in opposite directions beyond the nut h to which they are pivoted'and are connected/to links c'swiveled on the bearing g. `Thus as` the nut` 71, travels upwardly along tlie'threaded rodf the respective angles 0a between-the links 7c and levers j'are reduced.A Conversely when the pane a' is lowered, theangles are increased asthearmssepa'rate.' lThey tend to place spiral 'springs Z connected 'at one end to the pivots mand at their-other end to pins lc carried on-the links, under tension and this tension serves to cushion or 1 resist the 'downward movementgoff'thepane 7 to serve as a counterpoise'therefor;'

To facilitate the vremoval of the movable the end of the levers y' reciprocate Aare formed at their outer ends with portions as of enlarged diameter through which the enlarged heads {f2-on the pins j may pass.

It willthu'sbe seen th 4t a windshieldhas been-provided whereof one section is movable to provide ay Ventilating aperture in a; 'y

simple ma'nnerfrom actuating mechanism within convenient reach of anoperator` of the vehicle while 'the movable section itself is'providedwith a counterpoise counterbal- Y ancing the weight of the sectionwhich fasist a sudden closure ofthe opening which might shatter the glass. Various modifications may be made in theV configuration lof able section, a'vertical threaded rod, means to rotate the rod, Aa nut reciprocal along the rod, levers lpivotally connected at their respective ends tothe ymovable section and intermediate their ends to the movable nut,v

andlinks rotatableabout a point above .the

path of travel of the nut and pivotally ,conmi ice nected at their opposite ends to the 'tree ends of vthe levers,respectively.
